Jags place Mike Williams and others on IR

The Jacksonville Jaguars placed offensive tackle Mike Williams, a former first-round pick trying to revive his career, on injured reserve Tuesday along with five others.

Running back Greg Jones, cornerback Chris Roberson, defensive tackle Tony Williams, tight end Brian Jones and defensive end Elton Patterson also were placed on IR as the Jags reduced their roster to the NFL's mandatory 75-man limit.

Mike Williams signed a two-year contract that included a $1.4 million signing bonus in March, giving the Jags some much-needed depth along the line. For Williams, it was a chance to start over after four tumultuous years with the Bills.

But the 6-foot-6, 363-pound Texan missed most of training camp with a sore back, the same injury that caused him to sit out part of last season.

Greg Jones, the primary backup for oft-injured starter Fred Taylor, tore the anterior cruciate ligament in his left knee Saturday and will have season-ending surgery.

Roberson broke a bone in his shoulder Saturday. He won't need surgery but also won't be able to play until it heals.

Tony Williams has a torn biceps, Brian Jones sustained a knee injury during training camp, and Patterson hurt his shoulder.

The Jaguars released place-kicker Seth Marler and receivers Troy Edwards and Felton Huggins on Monday. They have to reduce the roster to 53 players by Saturday afternoon.
